    <p>I got the following problem:</p> <p>i have a method that requests an update from a websocket server:</p> <pre><code>public Playlist(Activity a) { this.activity = a; activity.setContentView(R.layout.player); KMC.c.send("MyPlayer::CurrentSongList('ID,ArtistName,Title,AlbumName')"); } </code></pre> <p>The result is succesfully received by the following function:</p> <pre><code>public void UpdateCPL(JSONArray jArray) { TextView TVti = (TextView) this.activity.findViewById(R.id.title); TextView TVar = (TextView) this.activity.findViewById(R.id.artist); TextView TVal = (TextView) this.activity.findViewById(R.id.album); ImageView IV = (ImageView) this.activity.findViewById(R.id.imageView1); Log.d("KMC.updateCPL", TVti.toString()); try { //Get the first item - not part of the listview JSONObject jObject = jArray.getJSONObject(0); String title = jObject.getString("Title"); Log.d("KMC.updateCPL", title); //works TVti.setText(title); //does not work TVar.setText(jObject.getString("ArtistName")); TVal.setText(jObject.getString("AlbumName")); IV.setImageResource(R.drawable.noimage); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } ListView LV = (ListView) this.activity.findViewById(R.id.listView1); LV.setAdapter(new listAdapter(this.activity, jArray)); } </code></pre> <p>My layout:</p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout android:id="@+id/relativeLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;TextView android:textAppearance="?android:textAppearanceLarge" android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_toRightOf="@+id/imageView1" android:text="@string/hello" android:layout_alignTop="@+id/imageView1" android:layout_alignParentRight="true" /&gt; &lt;TextView android:textAppearance="?android:textAppearanceSmall" android:id="@+id/artist" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@+id/title" android:layout_alignLeft="@+id/title" android:layout_alignParentRight="true" /&gt; &lt;TextView android:textAppearance="?android:textAppearanceSmall" android:id="@+id/album" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@+id/artist" android:layout_alignLeft="@+id/artist" /&gt; &lt;ListView android:id="@+id/listView1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@+id/imageView1" android:layout_alignParentLeft="true" android:layout_alignParentBottom="true" /&gt; &lt;ImageView android:id="@+id/imageView1" android:layout_width="90.0dip" android:layout_height="90.0dip" android:layout_marginLeft="5.0dip" android:layout_marginTop="5.0dip" android:layout_marginRight="5.0dip" android:layout_marginBottom="5.0dip" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>However, while i can log the result, TVti.setText(title); does not work as the text is not displayed.</p> <p>Anyone got an idea what the problem is?</p> <p>EDIT: Forget this, this isnt the problem. The problem is that the UpdateCPL method was not being called from the main thread.</p>

    1. COtry setting some static text into the field in your layout to ensure the problems isn't your layout.

    2. COI added the "hello world" string to the textview (and it is visible in the emulator). It is not replaced by setText().

    3. COIf i use setText() in the Playlist method, it DOES work.... so i think the problem is with accessing the activity or contentview?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
